Alkohole (I) werden mit N‐Hydroxyphthalimid (II) in Gegenwart des Betains (III) zu N‐Alkoxyphthalimiden (IV) kondensiert, aus denen durch weitere Umsetzung mit Hydrazin die O‐Alkylhydroxylarnine (V) freigesetzt werden.

The phase diagram for the binary system indium-tellurium has been clarified and corrected, particularly in the region near the composition InsTes. This material is a potentially important semiconductor, either alone or in combination with other materials, such as CusTe. AgsTe, CdTe, etc. Results of this study were obtained by correlating differential thermal analysis (DTA), chemical analyses of zone-refined ingots, microscopic analysis, and X-ray determinations. Two new phases have been identified, and the compositions of three other phases have been determined more precisely. (1) The phase InsTe (33.3 at. %Te) does not exist; the composition should be InsTe7 (43 at. %Te). The peritectic decomposition temperature is 462°C. (2) The phase InTe (50.0 at. oA Te) has the composition InsoTesr (50.8 at. 'A Te). The congruent melting point is 696°C. (3) A new phase InsTed (57.0 at. 'A Te) has been found having a peritectic decomposition temperature of 650°C. (4) The phase InaTes (60.0 at. o/o Te) has the composition InwTe4a (59.7 at. ok Te). The congruent melting point is 667"C, and there is a phase transition at about 550°C. (5) A new phase InsTea (62.5 at. 'A Te) has been found, having a peritectic decomposition temperature of 625"C, and a phase transition at 463°C. (6) The phase InsTeg (71.5 at. % Te) was prepared. (7) Electrical measurements on InsTeg show a large conductivity increase associated with the phase transition at 463°C. (8) Electrical measurements on zone refined InsTes, were non-reproducible.
